The Nets haven’t started a rookie on opening night in nearly 15 years, and it feels that long since Bojan Bogdanovic had a good shooting performance.

But the 25-year-old Croatian appears a fait accompli to be in the lineup when Brooklyn tips off Wednesday in Boston.

The rookie shot just 35 percent from the floor and 22.7 percent from 3-point range this preseason. But after waiting three years to get him into the NBA, the Nets are giving him every opportunity to succeed and coach Lionel Hollins fully understands how tough an adjustment Bogdanovic is being asked to make.

“When you’re just coming to a foreign country and learning a different culture — I know he speaks English, but it’s still a different culture — and it’s tougher, city life in New York, the NBA versus Europe, the rules are different, it’s an adjustment and he’s gotten more comfortable as we’ve gone along,” Hollins said.

“He’s progressing. It’s still a process, but I like what he’s done and I’m sure he’ll be a better shooter as we go along. He’s been a good shooter in Europe. But he’s a really good basketball player. I just want him to go out and be aggressive and make whatever play is there to make.”

Bogdanovic shot at least 46.3 percent in every one of his last three seasons at Turkey’s Fenerbahçe.

“It’s almost a whole new game,” Bogdanovic said. “I feel much better. I can’t wait to start the season. I’m very, very excited. … I know in [the] preseason I didn’t make a lot of shots, but I hope with the season I’m going to start to make it.”

Bogdanovic has started essentially all preseason, and would be the first Nets rookie to start an opener since Kenyon Martin in 2000.

“[He’s been] good, man. I thought he had a pretty solid preseason,” Deron Williams said. “Definitely, like anybody, some things to work on, and he’s still getting adjusted. But he’s doing great. He knows how to play the game; he can shoot it, he’s working on becoming a better defender, so he’s going to be a good rookie.”

Hollins played down the tape Williams has been wearing on his right (shooting) thumb/wrist.

“He got hit on it I guess, I don’t know,” Hollins said. “It hasn’t kept him from playing or being effective. It’s just bruise and bumps of playing in this league, you know. When he’s played, he’s played with it on and it hasn’t done anything with his shooting. It’s not even an issue.”
